It has for its principal objects to producev a strong, durable, simple and economical weatherproof hatch construction and to obtain other advantages hereinafter appearing.

In Figs. 1 to 5 of the accompanying drawings, 40 my invention is shown in connection witha metal i refrigerator car-roof comprising end and intermediate roof sheets I and 2, respectively, that extend from side plate 3 to side plate 3 of the car with their eaves ends resting on and riveted 45 or otherwise rigidly secured to the outstanding top flanges of eaves angles 4, whose depending fianges'are riveted or otherwise rigidly secured to the upstanding inner 'side flanges of lsaid side plates. The end and intermediate roof sheets 50 are providedalong their adjacent margins with upstanding flanges L5 that are straddled by a seam cap 6 that is `riveted or otherwise secured to said flanges and to the top anges of the eaves angles 4. At the end of the car, the end roof sheet 55 I vis. supported on andriveted or otherwise rigidly secured to theoutStanding top flange of an end angle l, whose*` depending `flange' is riveted or otherwise rigidly secured to they upstanding fiange of a metal endplate. 1 go The roof is provided with one or two hatch- (Cl. S-5) ways that lead downwardly through the end sheet I and a framework located therebelow into the interior of the car. Said framework comprises spaced parallel frame or carline members 9 that p extend from .side` plate to side plate of the car with their ends rigidly secured thereto by suitable brackets I. As shown in Figs. 3 and 5, these carline members comprise oblique metal angles disposed with one lflange extending laterally outwardly from the other flange and said other ange incliningdownwardly and inwardly.

Each hatchway opening is provided with a line members 9, and a hollow upper end rim portion or member I2 of substantially inverted channel-shaped section located above the general level of the roof and supported on tops of said carline members. The hopper member or portion II of the metal hatch frame A has its sides converging downwardly to rest fiatwise against the downwardly converging side flanges of the carline members 9 and to constitute a seat for a hatch plug (not shown) and is provided at its top vwith an outstanding ange I3; and the rim portion or member I2 of said hatch frame is of substantially Z-shaped section and is arranged with its top flange Iltextending inwardly to constitute a support for the outstanding flange i3 0f said hopper member. The top flange I3 of ythe hopper member I I is rigidly secured to the top flange I4 of the rim member by means of a weld I5 of added metal which extends continuously along the outer edge of the hopper flange.

The outstanding bottom or base ange I6 of the Z-shaped rim member or portion I2 of the hatch frame is supported on the two carline members 9 with its edges iiush with the edges of the top flanges of said carline members; and said hatch frame is rigidly secured to said carline members preferably by means of a weld I'l of added metal that extends along the iiush edges of said flanges and by means of welds I8 of added metal that extend along the lower edges of the depending side flanges of said carline members and the sides of the hopper portion or member II that ts therebetween. The end roof sheet has an upwardly offset portion or boss I9 that has a fiangeless opening 20 cut therein of larger size than the hollow rim portion or member I2 of the hatch frame. `The portion ofthe roof sheet boss I9 that surrounds the hatch opening 20 thereinoverlaps andis supported on the outstanding base flange I6 of the rim member I2 of the hatch frame; and said end or hatch sheet is secured to said base flange by means of a weld 2| of added metal that extends continuously along the edge of the hatchopening 207.111 said sheet.

v The construction illustrated in Figs. 6 and 7 is similar to thev construction h'ereinbefore described except that the hopper and rim portions o! the metal hatch frame are integral.

In the modication shown in Fig. s the rim member/of the metal hatch frame comprises a channel-#2a whose bottom or hatch sheet supporting flange ila rests uponfa wooden carline member 9a. The hopper member ila of this hatch frame forms a metal lining for a wooden hatch frame B and covers and protects the top thereof.

In the modified hatch construction shown in Fig. 9, the rim member IIb of the metal hatch frame is of Z-shaped section and surrounds the upper end of a wooden hatch frame B' -with its upper ilange Hb extending inwardly over the upper edge thereof and with its bottom or hatch sheet supporting iiange lib resting .on the wooden carline 9b. The hopper member lib of the hatch frame is disposed within the wooden hatch frame B' and has an outstanding top iiange lib that extends beneath the top ange lib of the rim member i2b and overlaps the upper edge of said wooden hatch frame.

The construction shown in Fig. 10 is similar to that shown in Fig. 9 except that the rim and hopper portions of the metal hatch frame are made integral.

In the modified hatch construction shown in Figs. 11 to 15, inclusive, the metal hatch frame comprises a bossed up portion, a hollow upstanding boss 23 surrounded by a fiat marginal portion 24 and having a hatch opening cut in its top that communicates with the upper end of a hopper member lic located in a wooden hatch frame B" that extends upwardly into and is covered by said boss. The base or marginal portion 2l of the bossed-up hatch frame rests upon the top of wooden carline members 9c and is provided with depending side flanges 25 that overhang the remote side faces of said carline members and are rigidly secured fiatwise thereto by means of lag screws or other fastening members 26. In this construction, like the constructions previously described, the hatch sheet is provided with an opening that surrounds the bossed-up portion of the hatch frame and is secured to the base flange of the latter by means of a weld that extends con-l tinuously around the edge of said opening.

The hatch construction hereinbefore described has numerous advantages. 'I'he metal hatch frame is reinforced and stiilened above the level of the roof by means of a hollow rim portion or boss and forms a rigid cross-connection between the carline members. The metal ,carline members cooperate with the hollow rim portion of the metal hatch frame to form strong hollow box girder sections along two sides thereof. The angeless opening in the hatch sheet is made large enough to accommodate misalinement of said opening and the metal hatch'frame. The weld along the edge of the opening in the hatch sheet forms a rigid weatherproof connection between the lapped portions of the hatch sheet and the base ilange of the rim portion of the metal hatch frame; and the location of the hatch sheet above said flange permits removal and replacement of said sheet without disturbing said hatch frame.
